I have to disagree with Revonut. A CD actually makes these overpowered MT hande the Brushless power alot better. (can keep the front wheels on the ground). To each his own, But I thought I should add this... Just because you got a CD doesnt make it just a racer... Just not a Crawler...
As you can tell I swapped to a CD as well... (100k oil though)
